It would start with a small crew rotating every two years and depends on radiation-safe habitats, closed-loop life support and local propellant. Larger settlement would follow only if supply costs fall.

What it brings

  • Field science on Mars geology and past life
  • Testing a self-sufficient settlement
  • Fuel production for onward travel
  • A stepping stone to the outer solar system
